Why Choose TENSAN Liquid Solder Flux?
1. Excellent Wetting and Solderability
TENSAN Liquid Solder Flux is formulated with carefully balanced activators that effectively remove surface oxides from copper, brass, nickel, and other common PCB finishes. This ensures rapid, uniform wetting, producing bright, well‑formed solder joints with minimal defects. Whether you are wave soldering high‑volume PCBs or performing selective soldering on dense assemblies, this solder flux delivers consistent, reliable performance.
2. Low‑Residue, No‑Clean Convenience
The solder flux system leaves a clear, non‑corrosive, and non‑conductive residue that does not require removal in most applications. This eliminates post‑soldering cleaning steps, reducing chemical costs, cycle time, and environmental impact. The low‑solids formulation ensures that residues are virtually invisible, supporting ICT and functional testing without interference.
3. Wide Process Compatibility
TENSAN Liquid Solder Flux is compatible with a broad range of application methods, including:
This versatility makes it suitable for both high‑volume production lines and low‑volume, high‑mix manufacturing environments.
4. Multi‑Alloy Compatibility
This Liquid Solder Flux works effectively with both lead‑free and tin‑lead alloys, including:
This broad compatibility simplifies material management and reduces the need for multiple flux formulations across different production lines.
5. Halide‑Free Formulation
TENSAN Liquid Solder Flux is available in halide‑free formulations, meeting strict environmental and reliability standards. This reduces the risk of ionic contamination and corrosion, making it ideal for high‑reliability applications in automotive, telecommunications, and medical electronics.
6. Stable Performance and Long Shelf Life
When stored properly in sealed containers, this solder flux maintains its performance characteristics for extended periods. The stable specific gravity and acid number ensure consistent flux activity, reducing the need for frequent adjustments and quality checks.

Frequently Asked Questions
Q: What is the difference between liquid solder flux and solder paste flux?
A: Liquid Solder Flux is a standalone flux applied separately from the solder alloy, typically used in wave soldering, selective soldering, or manual soldering. Solder paste flux is combined with solder powder in a paste formulation for SMT printing and reflow. TENSAN Liquid Solder Flux offers the same high‑quality flux chemistry in a convenient liquid form for through‑hole and mixed‑technology assemblies.
Q: Is this Liquid Solder Flux compatible with lead‑free alloys?
A: Yes. This solder flux works effectively with both lead‑free alloys (SAC305, Sn100C, SnAgBi) and traditional tin‑lead alloys, providing flexibility across different production lines.
Q: Does this Liquid Solder Flux require post‑soldering cleaning?
A: No. This is a no‑clean solder flux formulated to leave a clear, non‑corrosive, and non‑conductive residue that can safely remain on the board. Cleaning is not required for most applications.
Q: What is the shelf life of this Liquid Solder Flux?
A: Up to 3 years when stored unopened at 10–32°C (50–90°F). Always keep the container sealed to prevent solvent evaporation and contamination.
Q: Can this Liquid Solder Flux be used in foam fluxing systems?
A: Yes. This solder flux is compatible with spray, foaming, and drop‑jet fluxing systems, making it suitable for a wide range of production equipment.
Q: Is this Liquid Solder Flux halide‑free?
A: Halide‑free options are available, meeting strict environmental and reliability standards for automotive, telecommunications, and medical applications.
